Renesas Electronics Corporation ranks among the world’s leading semiconductor manufacturers. The company specializes in microcontrollers, analog chips, power devices, and system-on-chip solutions for automotive and industrial applications.
The Tokyo-based company formed in 2010 through the merger of NEC Electronics and Renesas Technology. Its origins trace back to the semiconductor divisions of three Japanese electronics giants: Hitachi, Mitsubishi Electric, and NEC.
Renesas holds the second position in the global automotive microcontroller market behind Infineon Technologies. The company serves major automakers including Toyota, Honda, and Nissan with chips that power everything from engine management to infotainment systems.
Renesas Electronics History
2002
NEC spun off its semiconductor operations as NEC Electronics Corporation. This marked the beginning of Japan’s semiconductor industry restructuring.
2003
Hitachi and Mitsubishi Electric combined their semiconductor divisions to form Renesas Technology Corporation as a joint venture.
2010
NEC Electronics and Renesas Technology merged to create Renesas Electronics Corporation. The combined company became the world’s fourth largest semiconductor maker.
2011
The Great East Japan Earthquake severely disrupted operations. Thailand flooding later that year caused additional supply chain problems for the company.
2013
INCJ (Innovation Network Corporation of Japan) led a ¥150 billion investment to rescue the company. Key customers including Toyota also invested in the struggling chipmaker.
2017
Renesas acquired Intersil Corporation for $3.2 billion. This purchase expanded analog and power semiconductor capabilities for industrial applications.
2019
Integrated Device Technology (IDT) joined Renesas through a $6.7 billion acquisition. Hidetoshi Shibata became CEO and accelerated the growth strategy.
2021
Dialog Semiconductor was acquired for $5.9 billion. A fire at the Naka Factory temporarily halted production but operations resumed within a month.
2024
Renesas completed the acquisition of Altium Limited for $5.9 billion. This marked the company’s expansion into PCB design software and electronic system lifecycle management.

Renesas Electronics Revenue
Renesas Electronics generated ¥1.35 trillion (approximately $9 billion) in revenue during fiscal year 2024. This represented a decline of 8.23% from the previous year due to softening demand in certain semiconductor segments.
Renesas Electronics Market Cap
Renesas Electronics holds a market capitalization of approximately $22 billion as of December 2025. The company’s valuation has grown substantially since its 2013 restructuring, though recent market conditions have caused some decline from 2024 peak levels.
Renesas Electronics Acquisitions
Renesas Electronics has pursued an aggressive acquisition strategy since 2016 to expand beyond its core microcontroller business. CEO Hidetoshi Shibata, a former investment banker, led this transformation that added analog, power, and software capabilities.
The acquisition of Intersil Corporation in 2017 for $3.2 billion marked the beginning of this expansion phase. Intersil brought power management and precision analog products that strengthened Renesas’s position in industrial and automotive power applications.
Integrated Device Technology (IDT) joined Renesas in 2019 through a $6.7 billion deal. IDT added expertise in timing, memory interface, and radio frequency products. This purchase expanded the company’s presence in data center and communications infrastructure markets.
Dialog Semiconductor became part of Renesas in 2021 for $5.9 billion. Dialog specialized in power management chips for mobile devices and brought strong relationships with major consumer electronics manufacturers. The deal also added Bluetooth and WiFi connectivity solutions.
Several smaller acquisitions followed, including Celeno Communications for WiFi technology, Reality AI for machine learning solutions, and Steradian Semiconductors for radar products. Transphorm, acquired in 2024 for $339 million, added gallium nitride (GaN) power semiconductor technology.
The Altium acquisition completed in August 2024 for $5.9 billion represented a strategic shift into software. Altium’s PCB design tools and cloud platform will support Renesas’s goal of creating an integrated electronics design ecosystem. Taiwan Semiconductor manufactures many of the chips designed using Renesas’s reference designs.
